The outcome

What actually happened.

The part

What it is

Checked at the horizon rather than when it happens to come up, so that the misses are recorded as well as the hits.

A reading that is right most of the time is worth acting on; one that is right half the time is a coin.

The smallest level

The attributes it carries

Each attribute is one of the framework’s shared types. What a date is, and how it is written, is defined once for the whole model — the note here says what it means in this particular place.
